MEMBRANE SUPPORTED CPW-FED WIDEBAND SLOT ANTENNA FOR MILLIMETER WAVE APPLICATIONS

Printed CPW-Fed Wideband Rhombus Slot Antenna for WiMAX applications

In recent years, wireless communications have progressed very rapidly. In order to provide with large bandwidth for any wireless application, wideband antenna design has become very important. In the reported literature [1-2], some of CPW-fed and microstrip-line-fed wide-slot antennas have been proposed for the wideband operation. The impedance bandwidths of the wide-slot designs [1-2] can reac...

Leaky CPW-Based Slot Antenna Arrays for Millimeter-Wave Applications

A uniplanar leaky-wave antenna (LWA) suitable for operation at millimeter-wave frequencies is introduced. Both unidirectional and bidirectional versions of the antenna are presented. The proposed structure consists of a coplanar waveguide fed linear array of closely spaced capacitive transverse slots. This configuration results in a fast-wave structure in which the = 0 spatial harmonic radiates...

Printed wideband CPW-fed slot antenna with high polarization purity

This paper introduces a novel compact wideband CPWfed slot antenna comprising of an E-shaped patch that is excited with a trident shaped feed-line structure. The antenna design exhibits a very wide operating bandwidth of over 168% with S11 < −10 dB in the frequency range 1.6 to 18.9GHz. The antenna’s radiation characteristics are stable across this wide bandwidth. The proposed antenna exhibits ...

CPW-Fed Circularly Polarized Slot ANTENNA with Elliptical-Shaped Patch for UWB Applications

A new design of coplanar waveguide (CPW)-fed antenna with circular polarization (CP) and excellent impedance matching is presented. In this design a pair of circular-shaped slits is applied to opposite corners of the slot for enhancing the impedance matching and realizes bandwidth of 134.43% across 2.98-15.20 GHz for VSWR≤2. Furthermore this structure exhibits axial ration bandwidth (ARBW) of 3...
